So the single-user mode from within LINUX is no option. Additionally I can't get PCMCIA and FireWire to work. So there is no other option than to do it within MacOS X (or 9?). Of course if I had a second LINUX partition, I could use your recommended commands from there, but still I haven't got the FireWire to work. So, is there a possibility to do it from MacOS X? > > > rsync, however, should do a fine job, provided you put all the right > options on it, and there are quite a few you need. > > You can also use dd (I was quite surprised at this!), provided that the > destination partition is not smaller than the source (you don't want to > loose data!).
